App comparative analysis based Android application store credibility evaluation method

An App comparative analysis based Android application store credibility evaluation method relates to the fields of software engineering and program analysis. The method is suitable for Android application programs. The application programs in an Android application store are subjected to sampling and comparative analysis to find out difference of different types, different weights are given according to different importance degrees, the application store is comprehensively evaluated by applying an evaluation algorithm, and an evaluation result and a relative sort order are given. The method comprises the following main steps of: selecting the application store and selecting an App sample set; building a virtual machine environment and collecting App samples; pushing an App installation file and obtaining basic information; performing comparative analysis on Apps in each application store and official Apps, and storing results; calculating a score of each application store; and finally performing result statistics. The method has the characteristics of wide application range, reasonability for evaluation, high automation level, convenience in use, visualization for result display and the like.
